TVS (Transient Voltage Suppressor) diodes are the go-to choice for wide range of transient voltage suppression applications. SMB10J24HE3/5B, a unique bi-directional TVS from Littelfuse, is designed to protect sensitive electronic equipment from high-energy, fast electrical transients, and voltage incorrectly wired to the board. This surge suppressor, with its non-linear capacitive refinement topology, is specifically designed to handle higher surge voltages than most ESD suppressors.

The SMB10J24HE3/5B includes a Zen Diode for ESD protection. This provides added flexibility within a single package, and helps reduce the board space if needed. The SMB10J24HE3/5B has an input voltage range of 4.5 V – 24 V and a working peak pulse current of 10A (minimum). It features over voltage and reverse flyback protection for circuit board and safety capacitors, and is compliant with the IEC 61000-4-2 standard for ESD (±20 KV contact, and ±30 KV air-discharge).

The SMB10J24HE3/5B comes with an adjustable threshold voltage that can be configured between 18.75V and 24V depending on the over voltage and reverse flyback protection needed. The threshold voltage can be adjusted with a single resistor just like a Zener diode, making it easy to use and energy efficient. The SMB10J24HE3/5B also has a very low leakage current of 15nA and a high clamping voltage of 38.5 V.

In terms of application fields, the SMB10J24HE3/5B is perfectly suitable for high voltage clamps in telecom, automotive, consumer electronics and computer power supply applications. Its versatility and wide operating voltage range make it the ideal choice in environments where a high level of surge protection is required. The SMB10J24HE3/5B can also be used as overvoltage protection circuits as well as in power conditioning circuits where high holding voltage and stableness are important.

The SMB10J24HE3/5B is designed to be bidirectional, meaning it can offer fast and effective protection from inrush currents and switching transients on either side of the device. It works by sensing transients on either side and triggering a reverse-conducting diode. This process is known as clamping, and is what gives the SMB10J24HE3/5B its superior reverse discharge protection. When the transient event has passed, the diode automatically turns off, allowing regular operations to resume.

In addition to being fast and efficient at protection, the SMB10J24HE3/5B is also highly reliable. Its low-capacitance variant eliminates the effect of parasitic inductance in the circuit, maximizing accuracy and reliability. The SMB10J24HE3/5B is manufactured to exacting standards using high-quality components, and is designed and tested to withstand high surge voltages.

Overall, the SMB10J24HE3/5B is a reliable and efficient surge protector for a wide range of applications, from Telecom and Automotive to consumer electronics and computer power supply systems. Its fast action and superior protection make it the ideal choice when dealing with sudden and unexpected power surges.
